Two of these small Moguls were still in use in 1947. The book says they were built by the railroad in 1888, and as such, Locobase believes, had dimensions and weights as shown in Locobase 9066. But it's clear from the data that they were substantially modified some time later.
As part of the CSCE President Samuel Keefer's address, he included information from Mr Brown, Mechanical Superintendent of the CPR that included the standard Mogul freight used east of the Rockies. Locobase has no other information than this account, but believes that the J3 engines shown superheated in Locobas 6553 were these engines.
